The short version

  • Each has a real cost: H2O.ai java is always required to run H2O-3 even when working from R or Python, and only a 64-bit JRE or JDK is supported; LOVO the vendor's own pricing page as captured by the Internet Archive on 6 December 2022 listed LOVO Studio at three tiers in US dollars: Free at $0 with 3 downloads per month and 3 day access to premium voices for personal use only; Personal at $17.99 per month paid annually (or $25.99 paid monthly, both promotionally discounted from $34.99/$49.99) capped at 15,000 characters per download and up to 30 downloads per month with commercial rights; and Freelancer at $99.99 per month paid annually (or $149.99 paid monthly) with up to 100 downloads per month and commercial rights; API pricing required a custom quote

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

H2O.ai

  • Java is always required to run H2O-3 even when working from R or Python, and only a 64-bit JRE or JDK is supported
  • Supported Java versions stop at Java SE 17; newer versions only run by forcing an unsupported version flag and are guaranteed for experiments rather than production
  • H2O-3 only supports numpy below version 2, so a numpy 2 environment must be downgraded
  • Supported Python versions are limited to 3.7 through 3.11
  • The Flow web UI requires an internet browser and is the only graphical interface

LOVO

  • The vendor's own pricing page as captured by the Internet Archive on 6 December 2022 listed LOVO Studio at three tiers in US dollars: Free at $0 with 3 downloads per month and 3 day access to premium voices for personal use only; Personal at $17.99 per month paid annually (or $25.99 paid monthly, both promotionally discounted from $34.99/$49.99) capped at 15,000 characters per download and up to 30 downloads per month with commercial rights; and Freelancer at $99.99 per month paid annually (or $149.99 paid monthly) with up to 100 downloads per month and commercial rights; API pricing required a custom quote
